I'm not sure they'll present Bitcoin 20k as the 'death of the dollar' but they could. I think more likely they start asking about the next crash and how volatile the coin is.

And then a few months / weeks later, they'll look like fools because BTC will be some insane amount like 50k or more. All the while, not realizing it was their news coverage about its volatility that helped push it that high. News is quite the comedy.
